I have used other repair company's before and always would cringe when they showed up in sloppy dirty clothes. Mark R. Came out in clean attire to tune up my 1972 furnaces and I new I could trust him when he didn't try to sell me a new furnace right off. Instead he let me know what other options are currently available and didn't push me like other repairmen. Thanks for your honesty Mark and I'll see ya next year as you recommended!
